not really, except maybe for dl_512_first.  sw_buffering means you want
the modem to do extra buffering (or maybe the opposite!), and as such
doesn't depend on the modem version.  The altsetting is indeed only
useful for people with old modems.  I know someone who insists he needs
altsetting 2 not 1, even though his modem seems identical to mine (based
on the contents of /proc/bus/usb/devices) - maybe a firmware difference,
but he says not.  So no known way to autodetect it (for most modems,
including my old one, altsetting 1 is better).  I don't know for dl_512.

Good defaults help (autodetecting them is nice too), but IMHO if an
option can be useful, it's better to have it.  Making configuration
easy is, in the end, a job for user-space tools...  I guess 
documentation may help.
